Cawthorne was identified with the cooperation of YMCA staff and the two victims after they saw surveillance video of the suspect, Olympia police spokesperson Laura Wohl wrote in a press release to local media.

A 10-year-old boy reported the troubling situation to the front desk at the YMCA around 4 p.m., and employees called police. After investigators arrived, a mother came forward and said the same thing had just happened to her 9-year-old son inside the locker room.

No word on whether there may be other victims. The case remains under investigation.

"It's very frustrating," Mark West, president and CEO of South Sound YMCA, told KOMO. "The safety and well-being of kids are of utmost importance to us. The little boy did the right thing and came out and reported the situation."
